VENT-BUNCE.

SPECIFICATION forming part of Letters Patent No. 267,598, dated November 14, 1882.

Application filed June 16, 1882. (No model.)

To all whom it may concern Be itknown that I, ADAM E. SCHATZ, a citizen of the United States ofAinerica, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Bung Bush and Vent; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to that class of automatic bungs that are provided with a mechanism thatis inserted into a properly-constructed bushing` for casks intended to contain effervescent or other liquids, and allows of the drawing off of the liquidwithout allowing the escape ofgases or other contents of the kegs, Src.

The invention consists in the construction and arrangementofparts, as will be more delinitely described hereinafter, reference being had to the accompanying drawings, in which- Figure l represents a plan or top view. Fig. 2 is a cross-section on line :l: w of Fig 1. Fig. 3 is a similar section on line y y of Fig. 1. Fig. 4 is an inverted plan view. Fig. 5 is a cross-section of one of the locking-cams or eccentrics. Fig. 6 shows the stopper or bung, Without the vent, applied to ajar.

Like letters represent like parts.

The essence of my invention is the mechanism that I employ as a locking device to keep the bung or stopper in place. The bushing A is provided on the outer side with the proper screw-thread or other means for fastening it into the keg or vessel. The interior of the bung A is provided at its bottom with a flange, a. which serves as a seat for the bung or stopper B. At theinner angle of the seat a, I cut a recess, so that a packing or washer, b, can be h'eld therein; but this not being essential, I have not shown it in the drawings. At the upper innerperiphery ofthe bush are provided two shoulders or lugs, 0. The bung or stopper, in the case where it is used as bung and vent, has a recess, d, in its bottom, which receives the rubber perforated disk C, that -is re tained in place by means of the spring e. On the upper side of the bung B are arranged two projectious,f, which form a round seat for the journal cam-bar D.

preferably two flat surfaces, g g, as best seen in Fig. 5, on each side, between which the journal or spindle part h is arranged. This journal or spindle part is placed between the two projectiousff, which form the seat which serves as a bearing for the cani-bar. The upperends of thetwo projections are then pressed together and the cam-bar is held securely in place. A curved lever, E, is so affixed to the earn-bar that when the device is locked the lever is in the position shown in the gures, and when open the flat sides g g of the cambar face the lugs c and allow of an easy removal ot' the bung or stopper. It is obvious that the cam-bar is sufficiently long enough to pass under the lugs c. The bung B is provided with suitable perforations, against which the perforated rubber disk is placed. These peri'orations are beneath or sidewise through one or both of the projectionsff, and are so arranged for the purpose ofprotecting the disk from injury from without.

I find in practice that by this means I can very quickly and efficiently close a bunghole in a cask after the same has been filled with beer. This is very essential to the proper preservation of the effervescence of the beer, since the quicker the bung-hole of a keg just filled is closed the less carbouicacid gas can escape, and the more effervescent will be the beer.

It is obvious that the cam-bar may be aiiixed tothe bung or stopper in a number of ways; but the construction I have shown I find to be the most suitable, and I do not limit myself to the exact construction shown in drawings.

It will be readily understood that this bush and bung-plate, with its locking cam-bar, can be used in larger-casks, such as are used as shaving, i'ermenting, or other casks.

It is also obvious that the packing is not essential, since vthe joint can be made accurate enough to form aJ tightjoint.

In Fig. 6 I have represented the bung or stopper B, with its locking-cam, applied to a jar. `The mouth or neck of thejar in this instance takes the place of the bushing A.

It will be readily seen that the device shown forms a much better and tighter joint, when applied in place, than the ordinary manner of securing the cap or equivalents to their This cam-bar has 1 seat by means of the compression caused by IOO the ealns. It cnn be manipulated with more rapidity and ease than any other known to in e.

Having thus described my invention, what I elaiin, and desire to secure by Letters Patent, 1s-

l. A bungplate, B, provided with zt looking Cain-bar, D, held in place between the projectionsff, arranged substantially as set forth.

2. The combination of the bung-bush A, having flange a and lugs c c, with the bung-plate B, provided with looking eem-bnr D, held in place by projections ff, arranged substantially as speeiied.

3. The vent-bung herein described, consisting of the bush A,l1aving the flanges a a, and lugs e c, under which the ends of loekingoambar D are held, which is secured to the bungplate by means of projeetionsff, said plate being perforated beneath or sidewise through one or both ofthe projeetionsff, in combination with a perforated disk, C, all constructed and arranged substantially as set forth.

In testixnonywhereofl afix my signature in presence of two witnesses.
